Considering the global environmental issues, various factors such as industrial ecology, eco-efficiency, and chemical engineering are being combined to develop advanced material known as bio-based or natural polymer-based materials. The environment and the cost-effective factors are now propelling the inclination in the direction of greater utilization of bio-based polymers and materials. Biobased materials are generally used to make industrial products and reliable goods. They are composed of a natural polymer, reinforced with agricultural waste, natural fibres and carbohydrates like starch, lignin, and cellulose. In this paper, we have discussed the introductory part of the biopolymers, e.g., cellulose, chitin, chitosan, PLA, and soy protein. Also, the mechanical properties of composites developed by using these biopolymers and their applications, specifically in the areas of biomedical and packaging sectors, have been discussed.

考虑到全球环境问题，工业生态、生态效率和化学工程等各种因素正在结合起来，以开发称为生物基或天然聚合物基材料的先进材料。环境和成本效益因素正在推动生物基聚合物和材料的更大利用的趋势。生物基材料通常用于制造工业产品和可靠的商品。它们由天然聚合物组成，并用农业废弃物、天然纤维和碳水化合物（如淀粉、木质素和纤维素）增强。在本文中，我们讨论了生物聚合物的介绍部分，例如纤维素、几丁质、壳聚糖、PLA 和大豆蛋白。还，
